ROTARY BOTTLING-MACHINE.

Specification of Letters Patent.

Patented Aug. 9, 1910.

Original application filed September 24, 1909, Serial No. 519,390.Divided and this application led March 9, 1910. Serial No. 548,225.

To all whom it may concern: v

Be it known that I, ANDERS ANDEnsEN PiNDs'roFTE, manufacturer, subjectof the Kingdom of Denmark, residing1 at No. 62 Frederiksberg Alle, in,the city of Copenhagen, Denmark, have invented new and usefulImprovements in Bottling-Machines, of which the following is aspecification.

rlhis application Vis a division of my former application filedSeptember 24, 1909, Serial No. 519,390, and the invention has for itsobject improvements in bottling machines and especially to provide suchmachines with means which successively and automatically release thebottles from the bottle filling devices in such a manner` that thefilled bottles can be removed and empty bottles inserted without it`being necessary for the operator himself to release the filled bottlesfrom or to press the empty bottles against the bottle filling devices,which of course essentially facilitates and accelerates the bottlingoperation.

The invention refers especially to bottling machines in which thebottles are placed upon movable bottle supports, which by means of acounterweight connected to the support by a chain or the like passingover a guide roll are drawn upward in an inclined direction therebypressing the mouth of the bottles firmly against the bottle fillingdevices.

The improved means consist of a lifting device operated by the machinebut being not connected to the bottle supports or to the counterweights,which lifting device during the rotation of the machine successivelylifts the counterweights so that the bottles placed upon thecorresponding bottle supports are released from the bottle fillingdevices', and further of means which receive the lifted counterweightsand cause that they remain inactive during the removal of the lledbottle and the insertion of an empty bottle, whereupon thecounterweights are again automatically brought into action therebypressing the new inserted bottles against the bottle filling devices.

A constructional form of the invention is shown in the annexed drawings,in which- Figure 1 is a side view of a rotary bottling machine providedwith the improvements, certain parts being omitted. Fig. 2 a sectionalplan view of said bottling machine,

certain parts being omitted, and Fig. 3 a vertical section through apart of the machine.

In all of the figures a is the rotating part or carrier of the bottlingmachine, which is operated by means of the screw b and pinion c. Themovable bottle 'supports ci are drawn upward by means of counterweightsc connected to said bottle supports, so that the bottles placed upon thebottle supports are pressed against the bottle filling devices f.

The machine is provided with a lever g having' its free end situatedbelow the path of movement of the counterweights e and being fulcrumedto permit a certain lateral movement, thereby permitting the lever tofollow the rotating conterweight within a certain distance. To a shaft7L placed below the lever g and rotated from the driving shaft of thebottling machine is fixed a cam v1 or the like which for each revolutionof the shaft lifts the lever g which in turn lifts the counterweightbeing above its free end at that moment and places it upon a guide railla, thereby causing the bottle support d to move downward and releasethe bottle from the bottle filling device f (see Fig. 3) so that thefilled bottle can be removed from and an empty bottle inserted upon thebott'le support.

It will be understood that any suitable valve mechanism is employed forcontrolling the flow of liquid, through the bottle filling means f', butthis element is not referred to in the claims, and forming no part ofthe present invention has not been illustrated on the drawings.

The guiderail causes the count'eiweights e placed upon it to beinoperative until they again owing to the rotation of the machine havepassed the other end of said rail, whereupon the counterweights areagain brought into action and press the empty bottles inserted upon thebottle supports against the bottle filling devices. As soon as the camz' has passed the lever g said lever falls at once down upon the hub ofthe cam i (see the position shown in broken lines Fig. l), so that thelever g, when lifted again by the cam i, will meet the nextcounterweight and lift it.

The above constructions can be modified without departing from the scopeof the invention, and the specific form of elevating means may be usedin connection with movable carriers Whether rotary or otherwise movable.

The invention is especially intended for rotary counterpressure-bottlingmachines in which the countervveights owing to the great pressure mustbe very heavy. In such cases the lifting by hand or foot of thecounterweights is of course a very tiresome and timewasting Work, whichhitherto has essentially diminished the capacity of such machines..These disadvantages are however' prevented by the invention as by it theliftingof the c'ounterweights is automatically. performed so. thatthereby the capacity of the machine is more than doubled. And further.the manual labor demanded of the operator is essentially diminished ashe can give full advertence to the bottles and consequently the exchangeof bottles can be done more rapidly than hitherto.

Claims.

l. In a rot-ary bottling machine having a number of bottle fillingdevices and a corresponding number of' movable bottle supports, thecombination With counter-Weights, one for each ofthe bottle supports andeach connected to the corresponding bottle support` by a chain passingover a guide roll, of

alifting device independent of said bottle supports and counterweights,which lifting device is operated in accordance with but fullyindependent of the bottling machine to lift successively during therotation of the machine said counterweights thereby successivelyreleasing the bottles placed upon the bottle support from the bottleilling devices, and means Which receive the lifted eountervveights andkeep them inoperative dur-ing the removal of a filled and the insertionof an empty bottle Where upon said means again automatically cause thecounterweights to be active and press the bottles against the bottlefilling devices.

2. In a bottling machine, the combination of a. movable carrier, aplurality of bottle supports movably mounted thereon, counter- Weightsconnected with said supports and normally holding same in the fillingposition, automatic means elevating said counter- Weights comprising alever operating in the path of said counterweights, means temporarilyholding said counterweights elevated independently of said automaticmeans, means operating said movable carrier, and means operating saidlever, substantially as described.

3. In a bottling machine, the combination of a movable carrier, aplurality of bottle supports movably mounted thereon, counter- Weightsconnected with said supports and normally holding same in theillingposition, automatic means elevating said counter- Weights comprising alever operating in the path of said counterweights, means temporarilyholding said counterweights elevated independently of said automaticmeans, means operating said movable carrier, and means operating saidlever comprising a cam rotating beneath and in engagement with saidlever, substantially as described.

4. In a rotary bottling machine having a number of bottle fillingdevices and a corresponding number of movable bottle supports, thecombination with counteruf'eights one for each of the bottle supportsand each connected to the corresponding bottle support by a chainpassing over a guide roll, of a lever fulcrumed in the frame of themachine and having its free end below the path of the counterweights, acam or the like fixed to a shaft rotated in accordance with but fullyindependent of the rotation of the bottling machine, which cam lifts andagain suddenly releases the lever for each full revolution of theshaftthereby causing the lever to successively lift the counterweightsand thereby successively to release the iilled bottles placed upon thebottle supports from the bottle fil-ling devices, and a guide rail whichreceives the lifted counterweights and keeps them inoperative during acertain time whereupon it again brings the counter- Weights into actionso that the empty bottles inserted upon the bottle supports are pressedagainst the bottle filling devices.

In testimony whereof I, ANDERS ANDERsnN PiNDs'ror'rn have signed my nameto this specification in the presence of two subscribing Witnesses, this15th day of February 1910.
